Context. The connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still debated. Aims: We aim to obtain new...

Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of the BL Lac object S4 0954+65 with data acquired in...

We present Gemini/GNIRS (Gemini Near-Infrared Spectrograph) spectroscopy of the Seyfert 2 galaxy NGC 4388, with simultaneous coverage from 0.85 to 2.5 μm...

Recent observations from integral field spectroscopy (IFS) indicate that the fraction of galaxies that are slow rotators (SRs), FSR, depends primarily on...

Using the exquisite depth of the Hubble Ultra Deep Field (HUDF12 programme) data set, we explore the ongoing assembly of the outermost regions of the most...

Aims: The chemical evolution of galaxies on a cosmological timescale is still a matter of debate despite the increasing number of available data provided by...

We present the results of a near-infrared imaging study of the host galaxies of 17 quasars in the redshift range 1 RLQ(host)=-27.55+/-0.12 and K>RLQ(host)=-26...

This work investigates the connection between the cosmic web and the halo distribution through the gravitational potential at the field level. We combine three...

Aims: We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the...
